Petals around the rose
I got this puzzle from Geoff Appleby blog

pretty cool, I'm sending it to my friends
http://crux.baker.edu/cdavis09/roses.html

There are five dices

the rules are simple:
- you roll the dices
- and then enter how many petals you think there are around the rose
- press "check" to verify your answer
- repeat the steps until you get consistent correct answers
- Once you have figured it out, don't spoil the fun for others

just for the record, it took me 3 attemps to make a correct guess, then I confirmed it in the fourth and fifth, which according to "Dr Duke", I'm not very smart =o(
